Terraform Day 6 Knowledge Check

In your Terraform configuration, you have two resources: an Azure Storage Account and an Azure VM instance. You want to ensure the VM instance is provisioned only after the Storage account is successfully created.

Which Terraform attribute should you use to establish this dependency?

• requires

• after

• depends_on

• connected_to

Which of the following is an example of a provisioner in Terraform?

• • remote-exec

• • state-management

• • config-sync

• • cloud-run

When should the local-exec provisioner be used?

• • To execute a command on a remote machine

• • To execute a command on the machine running Terraform

• • To manage Terraform state files

• • To deploy resources to a cloud provider

Which scenario would require the use of the provider meta-argument?

• Deploying resources in multiple Azure regions with a single configuration.

• Writing a custom provider plugin.

• Importing existing resources into Terraform state.

• Running terraform plan to preview changes.

What is a primary use case of a null resource in Terraform?

• Creating dummy resources to meet provider requirements.

• Managing resources that are no longer required.

• Using provisioners or triggers without creating actual infrastructure.

• Debugging Terraform plans.

In a null resource, what role do triggers play?

• They define dependencies between resources.

• They force re-creation of the null resource when their values change.

• They determine which provider to use for the resource.

• They are used to run provisioners conditionally.

Answer explanation

The triggers argument in a null resource is used to define dependencies. If any value in triggers changes, the null resource is destroyed and recreated.

Which of the following is correct about the terraform import command?

• It creates a new resource in Terraform's state and in the cloud provider.

• It imports an existing resource into Terraform's state file.

• It imports an existing resource into the Terraform configuration file automatically.

• It creates a backup of the resource before importing.

After running terraform import, what additional step is required to fully manage the resource in Terraform?

• No additional steps are needed.

• Run terraform plan to refresh the state.

• Manually add the corresponding configuration for the resource in the Terraform configuration file.

• Destroy and reapply the resource to match the configuration.

Which limitation applies to the terraform import command?

• It does not support azure resources.

• It cannot import multiple resources simultaneously.

• It deletes the resource from the cloud provider after importing.

• It automatically creates missing dependencies.

Which statement about remote-exec provisioners is true?

• They can only be executed on Linux-based systems.

• They require an SSH or WinRM connection to the target machine.

• They execute commands only during the destroy phase.

• They are mandatory for all Terraform configurations.
